Virus?

[Shlup]

Every once in a while my computer gives me the following warning:

So I run the suggested program, and it finds nothing. I run Search and Destroy, and that finds nothing. I Google the name of the .exe and that gets no results. I type the file path into explorer and it says there's no such thing.

So how do I make it shut up?
